Are Coolant and Antifreeze the Same Thing?

Coolant and antifreeze are the same with no difference. The full name of antifreeze is antifreeze coolant. Here are the related introductions: 1. May cause cylinder block cracking: Prevents freezing when the vehicle is not started, because antifreeze is in the cylinder block. When liquid turns into solid, its volume expands, which can crack the cylinder block. 2. Effects of deteriorated antifreeze: Cools the engine after the vehicle starts to prevent engine overheating and damage. Long-term failure to replace antifreeze will lead to changes in its quality, reducing its internal anti-rust properties, and damaging the radiator and pipes. It will also affect the boiling and freezing point parameters, impacting the antifreeze or cooling effect, and causing harm to the engine. Do not wait until the antifreeze turns black to replace it. Black antifreeze indicates severe deterioration.

How often should a sedan be inspected after 10 years of use?

Sedans that have been in use for ten years require an annual inspection. Additional information: Starting from November 20, 2020, non-commercial small and mini passenger vehicles (excluding minivans) that are over 6 years but less than 10 years old have their inspection cycle relaxed from once a year to once every two years. This means that private cars within 10 years only need to undergo two on-site inspections, specifically in the 6th and 8th years. For private cars older than 10 years, the original inspection cycle still applies: vehicles aged 10-15 years require an annual inspection, while vehicles over 15 years old require inspections every six months. Below are some important notes for vehicle inspections: 1. Inspection timing: The inspection date for each vehicle is indicated on the vehicle registration certificate. Inspections can be conducted up to three months in advance, but delays are not allowed. Even a one-day delay is considered overdue. If caught by traffic police, a fine of 200 yuan and 3 penalty points may be imposed. 2. All traffic violations must be resolved before the inspection; otherwise, the vehicle cannot undergo the inspection. 3. Any modified parts on the vehicle, such as lights or other components, must be restored to their original condition, or the inspection will not pass. 4. If a vehicle misses three inspections, it will be subject to mandatory scrapping.

Are Car Horns Waterproof?

Horns are not waterproof. Once water enters the horn, it can significantly weaken its warning capability, such as making the horn sound softer, hoarse, or even causing it to stop working entirely. Below are methods to address severe water ingress in horns: 1. Use a hair dryer to dry: For horns located in accessible positions where a hair dryer can reach directly, you can use the hair dryer to heat the internal moisture, promoting rapid evaporation. Of course, once the moisture evaporates, the horn's sound will return to normal. 2. Disassemble and clean: Remove the horn directly and thoroughly clean the internal moisture. Since most vehicle horns are located inside the bumper, it is difficult to remove the horn without dismantling the bumper. Therefore, disassembly and cleaning should be performed at a professional 4S shop.

Where is the air intake for the internal circulation located?

The air intake for the air conditioning system's internal circulation is located on the passenger side, beneath the glove compartment on the dashboard. Here are some related details: 1. Advantages: Internal circulation primarily serves to promptly and effectively prevent external dust and harmful gases from entering the vehicle, such as when driving through areas with smoke, dust, unpleasant odors, or in heavy traffic where it blocks harmful exhaust emissions from the vehicle ahead. Internal circulation also enhances the cooling and heating efficiency of the air conditioning system and provides better insulation. 2. Disadvantages: Prolonged use of internal circulation can degrade the air quality inside the vehicle, potentially causing dizziness or discomfort. It is advisable to switch to external circulation for a few minutes after using internal circulation for a while, allowing fresh air to enter the vehicle and improve air quality.

What is the Difference Between a Garage and a Parking Lot?

The differences between a garage and a parking lot are as follows: 1. Garage: A garage is an enclosed space where vehicles can enter and exit, equipped with doors that can be opened and closed. Garages can be either above-ground or underground. The advantage of a garage is that it helps keep the vehicle clean, while the downside is the high cost of purchase or rental. 2. Parking Lot: A parking lot is a designated area for parking vehicles. Parking lots can range from simple ones with just marked parking spaces and no management or fees, to fee-based ones equipped with entry and exit barriers, parking attendants, and time-based payment collectors. Modern parking lots often feature automated time-based payment systems, closed-circuit television, and video recording systems.
